Outcrop Analogues for CO2 Storage (Devon and Dorset, UK)
Format and Duration:
5 days
Using outcrop studies, participants will consider the effects of reservoir geometry, porosity, permeability, and geomechanical properties on CO₂ flow patterns, storage, injectivity, reservoir strength, and behaviour at high fluid pressure. Analogues to top-seals for CCS sites will be considered, plus fault reactivation at elevated CO₂ pressure, well design, and completions strategies.
Business impact: Participants on this field course will learn to apply outcrops along the Devon and Dorset coast as geological analogues for some major CCS projects including Hynet (Hamilton), Endurance, Acorn/Goldeneye, and East Mey.
Schedule
Duration and Training Method
This is a field course supported by short classroom sessions. Discussion and hands-on exercises will be conducted at all field localities.
Course Overview
Learning Outcomes
Participants will learn to:
- Detail the effect of reservoir properties on CO₂ storage capacity and CO₂ injectivity.
- Examine the influence of reservoir heterogeneity on CO₂ movement patterns.
- Explain how faults with different orientations and geometries may undergo reactivation at elevated CO₂ pressures.
- Develop strategies for considering possible CO₂-water-rock reactions depending on host rock mineralogy and fluid chemistry.
- Evaluate CO₂ well completions strategies.
- Appraise top-seals in terms of their lateral and stratigraphic variability of geomechanical and petrophysical properties.
- Develop approaches for considering the possible extent of reservoir dilation and reservoir fracturing due to elevated CO₂ pressure.
Course Content
The field course will visit reservoir and top-seal analogues to consider the following key topics:
- How reservoir geometry will affect CO₂ flow patterns.
- The effect of reservoir permeability on CO₂ injectivity.
- How reservoir porosity affects CO₂ storage.
- The effect of geomechanical properties on reservoir strength and behaviour following CO₂ injection (i.e., reservoir dilation, fracturing) at high fluid pressure.
- Reactions that may occur in sandstone and carbonate reservoirs, focussing on the rate and likelihood of dissolution versus precipitation of minerals.
- Top-seals for CCS sites - geometry, heterogeneity, permeability, capillary entry pressure, and advective CO₂-loss, CO₂ diffusive loss, and fracturing at elevated CO₂ pressure.
- The effect of stress orientations in the subsurface relative to fault orientations and the possibility of fault reactivation at elevated CO₂ pressure.
- The influence of rock properties on CO₂ injection well design and completions strategies - weak (friable) vs. relatively strong (brittle) lithologies.

Richard Worden
Background
Professor Richard Worden is leader of the Diagenesis Research Group and programme director of the MSc on Petroleum Reservoir Geoscience at Liverpool University. He has more than 30 years of industry and research experience.
Prof. Worden undertook a BSc in Geology and Geochemistry at the University of Manchester, completing it with a 1st class honours degree in 1984. Following a PhD at Manchester University in 1988, he worked for BP Research and BP Exploration in Sunbury, UK, for 6 years. This was followed by a lectureship at Queen’s University in Belfast until 2000 and then a professorship at Liverpool University.
Richard has worked on a number of areas of research, almost all related to oil and gas geoscience, with focus on high quality reservoir-scale data (including quantitative mineral and textural data, and the integration of petrophysical, petrographic, geomechanical, geochemical, and sedimentological data) to help with oil and gas exploration, appraisal and asset management. He has worked extensively on sandstone reservoir quality throughout his career, with focus on the causes of anomalous porosity-preservation in deeply buried sandstone reservoirs. His research is now extending into reservoir property-related issues involved in the energy transition (CCS, hydrogen generation and storage). He has published seminal papers on the role of microquartz coatings and on the effects of early oil emplacement on quartz cementation, with a key paper on chlorite-inhibition of quartz currently in press with the Bulletin of the American Association of Petroleum Geologists.
